CLELLN 7' TOP/VE YS vPatented June 26, 1951 BALING PRESS, ESPECIALLY BALE CASE CONSTRUCTION George B. Hill and. Marcus E. McClellan, Ottumwa, Iowa, assignors to Deere Manufacturing Co., Dubuque, Iowa, a corporation of Iowa Application May 3, 1948, Serial No. 24,894 Y 19 Claims. (Cl. 100-19) This invention relates to a baling press or the like and more particularly to improvements in the bale case to prevent malfunctioning of certain of the baler parts because of distortion of the bale case.

The usual baler is most economically constructed on the basis of a design including an elongated bale case made up of a plurality of sheet metal walls defining a generally rectangular chamber in which a plunger reciprocates to form bales of the material being handled.V Ordinarily, the top wall of the bale case carries tying mechanism and a needle is carried by the bale case for movement into, and out of an opening through the bottom wall of the bale case for handling a tying medium, such as wire or twine, which is caused to enter the bale case through the bottom opening and through an opening in the top wall proximate to the tying mechanism. The tying mechanism and needle must be appropriately timed with the baling plunger and with each other so that the tying operation is effected at proper intervals in accordance with the quantity of material in the bale case and in relation to the functions of other parts of the baling mechanism. Because of the generally flexible nature of the bale case, it often happens that cooperating parts of the tying mechanism, including the needle, become misaligned, especially when the baler is of the pickup type and is moved over uneven ground, in which case it will be appreciated that the distortion of the bale case has an adverse effect on the tying mechanism, particularly on the needle, which in many cases is jammed in its guide slot, or the twine or wire that it is feeding slips out of the guiding rollers and becomes wedged between portions of the needle and portions of the bale case. It will further be appreciated that the foregoing malfunctioning is a constant source of annoyance to the operator and results in numerous break downs and considerable loss of time.

According to the present invention, it is proposed to eliminate the disadvantages by the provision of an improved bale case structure embodying rigid supporting elements for the tying mechanism components. Particularly, it is an important object of the invention to provide a unitary rigid support for the tying mechanism which is preferably in the form of a casting having generally a saddle-like construction provided with rigidly joined parts securable to related walls of the bale case in such manner as to reenforce the bale case in the vicinity of the tying the needle.

2 mechanism, thereby eliminating distortion of the case at that point. A related object has to do With the provision on such support of means for mounting ythe tying mechanism independently of the bale case, so that flexing or distortion of the bale case will not be carried to the tying mechanism. It is a further related object to mount the tying needle on such support. Inasmuch as prior constructions depend upon structural parts of the bale case itself to define the guide slots through which the tying needle travels, it will be readily understood that distortion or flexing of the case would naturally affect the guide slots to such an extent that the slots allowed the wire or twine to escape from It is an important object of the present invention to provide a rigid needle guide having slots dene'd byrelatively rigid portions that will not be affected by flexing or distortion of the bale case and which consequently will not interfere with proper operation of the needle and proper feeding of the wire or twine. A related object of the invention pertains to the provision on such support of mounting means whereby the support may be easily attached to the bale case.

The invention contemplates further the provision in a bale case structure of a pair of rigid supports of the type referred to and related in such manner in the bale case structure as to reenforce and rigidify the portion of the bale case in which the tying operation takes place. "In order that the rigidity afforded by the supports does not altogether eliminate desirable flexing of the bale case, the invention includes the features based on the designv of the supports in such manner that they may be secured to the bale case at relatively few points, certain of the supporting connections being in the form of single mounting elements providing'for exing of the -case without transmission of the torsional deflection of the case to the support, thus eliminating the danger of breakage of the support.

The foregoing and other important objects and desirable features inherent in and encompassed by the invention will become apparent as the disclosure of a preferred embodiment of the invention is made in detail inthe following description and accompanying sheets of drawings, in which Figure 1 -is a fragmentary perspective view showing the upper intermediate portion of the bale case of one well known type of baling press;

As best Vseenin :Figures 1;'.4 and-gthe bale l*case :is of elongated 'characterandisgeneraily lrec- .ftangular in-crosssection; havingfour walls preferably constructed'fof'sheet 'metal and varranged :to formr the rectangular"balingA chamber, the -walls being:indicated'generally 'as a top wall!!! .'(Figure l), a b'ottomrwal'l'l "(Figure.6) 4andnpposite side1wallsf22iand23. Theinteriorfof the case isthus' in the' 'form of. a chamberfto which .'material is'fed vtoibe compressedintobalesby a rreciprocating vplungerI (not shown) ein thel usual marmer.

According to' theinventionthere'is provided l a"flrs't support, designated'generally.bythe numeral 25 and shown by itsl'frin Figure 3. This support is preferably'intne/form-rof a casting so Athat it provides a rrigid-unitary 'structurexand is .shaped generally as a saddle,n the details of which `Will-presently appear.' Thelupper'portion- 'of the fmember 25 is of open :construction which provides a rigid generally vrectangular.` frame struciturev madey vup of arpair of-opposite generally parallel side Lelementsf` 26 and '21 and al pair of transverse end elements '128 and29. 'That part ofA ther member '251 'comprising the elements f26, 2T, 28.'and V2li provi'desran upper'itransverse part "which is adapted to i' be Y'disposed' `.transversely across the top'wall 2|! of'r thefbaleca'se' (Figure ,1) "Themember k"25 further includes aipairof depending parts in' the :form fof arm portions 3Q rand'3l respectively rigidly'joined to and depend- :ing'frornl the side elements .2E and V21. The junc- ':tionbetween the side element 26 and the depend-` `ingt'armportion 3091s enlarged or reenforced at y-32 to reenforce the structure :generally and to .-'accommodate theprovision'of a recess or pocket 33. The opposite side of the structure is similarly rpro'vi'dedwith` a reenforcement or second por-tion i234 which has aspocketiorrecess'35. The end'ele- 1ment228 is-langed ati3E-andthis flange is providedfwith a mounting aperture 31, the-purpose of which will presentlyappear. fTheltransverse `Lor end element`29 isiprovided with an intermediin Figure 1.

4 ately disposed upstanding apertured ear 38 which provides a supporting or bearing portion in transverse alignment with an apertured ear 39 which extends substantially as a continuation of the side element 28 substantially at the junction between that element and the depending arm portion 3|. Each of the lower portions of the Adepending arms 34 and 3i is apertured, only the aperture in the arm 3l being visible at 46 in Figure 3.

The member 25 is mounted on the top of the bale case with the side elements 26 and 21 re- *spectivelyI paralleling the bale case side walls 23 and'22 and with the end elements 23 and 29 lying-.transversely across the top wall 2Q; the side parts or arm portions 30 and 3l depend respectively alongside the side walls 23 and 22 (Figures land 2). The upper or transverse part of the member '25 is secured to the bale case preferably by means of a single point of connection between the member andthe bale case top wall 20, a bolt and nut being used for this purpose,the bolt passing through the aperture 37 in the flange 36 on the end element 2S (Figures 1 and 3).

As best shown in Figures 5 and 9, the side wall portions 22 and 23 are reinforced respectively at 46 and 4l by means oa short longitudinal strip preferably secured to-the bale case Walls by welding. The reenforcing strip 4S is proximateV to the lower end of the depending arm portion 3i and serves as part 'of a mounting means, including a bracket 48, for .connecting the arm 3i to the bale case wall 22. As best shown in Figure 9, the bracket 48 is generally in the form of a Z having an apertured flange through which bolts 49 are vpassed for securingthe bracket to the bale case wall, the bale case wall and reenforcing strip 46 being appropriately apertured in alignment to receive these bolts. The bracket t3 carries a mounting pin 5B which passes through the aperture 46 in the arm 3l and thence into aligned apertures inthe reenforcing strip le and the proximate portion of the bale case wall 22. The pin 58 is preferably welded at its outer lend to .one of the nanges ofthe bracket 43 and the bracket and pin may be considered a unitary element for the purposes of assembly. and disassembly, removal of the bolts `49 permitting'removal of the bracket 48 and withdrawal oi the pin 5! from the arm 3|. 'The other arm 33 is connected to the other bale case. side wall 23 by similar means, indicated -in itsentirety by thev numeral 5I The member 25 is thus carried by the bale case at the three points 45, 5e and 5l and these means serveV to carry the member 25 so that it may be easily removed and installed.

'When the member 25 is in place onthe bale case it becomes a structural part of the bale case and serves as means for carrying the baler tying mechanism, as best shown in Figures 1 and 2. .It will be understood, of course, that any type of tying mechanism may be carried on the saddle member 25 and the details of the mechanism illustrated form no part ofthe present invention. A comparison of Figures 1 and 3 will illusxed thereto a pair of operating cranks 58 and 59, which are disposed respectively laterally outwardly of the member side elements 26 and 21. The apertured ears 38 and 39 provide bearing means for carrying a transverse shaft 60 which, through a sprocket and chain connection 6|, drives a short parallel shaft 62 journaled in brackets 63 that are mounted on the top wall 20 of"the bale case, this latter structure being the only part of the tying mechanism that is not carried entirely on the saddle member 25. The forward portions of the side elements 26 and 21 are respectively provided with mounting portions 64 and 65 (Figure 3) on which is carried a housing 66, this housing having ears 61 and 68, respectively, carried on the mounting portions 64 and 65 by means of bolts 69 and 10 (Figure l). That portion of the bale case top wall 20 immediately below the housing 66 is open, as indicated generally by the numeral 1| in Figure 1, this opening being provided for the purpose of feeding wire or twine into the baling chamber by Afeeding means carried by the housing 66 and member 25. The numerals 14 indicate a pair of.

tubular wire guides for directing wire or twine (not shown) to the mechanism within the housing 66.

may be of any conventional construction and which are arranged to move into and out of the bale case through the bottom opening 00 as the needle frame 8| pivots about its transverse axis as aforesaid. The purpose of the needle is to `which a strand of wire or twine, as at 90, is

trained. The pulleys 88 carry the wire 90 up into the bale case, in the usual or well known manner. The wire or twine is supplied to the needle by dispensing mechanism (not shown), the wires being trained over a pair of laterally spaced pulleys 9| carried on brackets 92 secured to a transverse carrier member 93. The latter member is generally of U shape (Figure 6) and is rigidly secured to the bale case preferably by means of being welded to the bottom wall 2| and opposite side walls 22 and 23. The oscillating movement of the needle assembly aboutthe transverse The transverse shaft 51 is chain-driven by means of a sprocket and chain mechanism, indicated generally by the numeral 15, just inwardly of the cam 59. An appropriate shield 16 is provided for enclosing a substantial portion of the chain drive means. Although the saddle member 25 illustrated here is based upon a design permitting the use 0f this member as an accessory or attachment for existing balers and is especially adapted to carry the tying mechanism illustrated, it will be appreciated that changes may be made in the design thereof for the purposes of adapting it to other balers and other types of tying mechanism.

In the type of baler illustrated, and in other conventional balers, the tying mechanism cooperates with a needle that moves alternately in and out of the bale chamber through an opening in the bottom of the bale case. The bottom opening in the present instance is indicated by thenumeral 80 and is best shown in Figures 5, 6 and 8. The needle is carried on a needle frame, indicated generally by the numeral 8|, which prei'- erably comprises a bail having a transverse portion 82 and a pair of arms 83 and 84. The kupper end of the arm 84 is provided with pivot means including a bearing or sleeve 85 (Figures 5 and 9) carried by the pivot pin of the bracket 48, the structure thus providing a combined mounting means for carrying the needle frame arm 84 and the saddle member 25, the latter through the medium of the depending arm or part 3|. The other needle frame arm 83 is similarly carried at the opposite side of the bale case by the bracket and pivot means 5| (Figure 1). The needle frame is thus carried by the bale case structureffor swinging about a transverse axis through the aligned carryingmeans 50 and 5|.

The transverse part 82 of the needle frame 8| carries a pair of parallel needles 86 and 81, which axis through the pivot or mounting members 50 and 5| is effected by thecranks 58 and 59, these cranks being respectively connected by pitmans 95 and 96 to the needle frame arms 83 and 84.

In prior constructions the bale case bottom was provided with a pair of slots for respectively receiving the free ends of the needles, and in many cases it was found that iiexing of the bale case would distort these slots to an extent suicient to permit the wire or twine to escape from the needles and become wedged between the needles and portions of the bale case bottom. According to the present invention, this possibility is eliminated by the provision of a rigid and unitary support providing a needle guide member which positively guides the needles 86 and 81 into and out of the bale case. The needle guide member or support is best shown by itself in Figure 1 and is indicated in its entirety by the numeral |00. This member includes a main body portion of at or plate-like construction, although preferably formed as a casting. The main body is provided at one end with a mounting ear |0| which has single aperture |02 formed therein. The opposite end of the member has a mounting ear |03 which is apertured in two places, as at |04. When the member |00 is installed in place over or within the opening in the bale case bottom wall 2|, the mounting ear |03 is mounted on the transverse carrier element 93, previously described, the latter having a pair of apertures |05 cooperable with the apertures |04 to receive a pair of bolts |06 (Figure 5). The mounting ear |0| serves as means for supporting the member |00 on a second transverse carrier element |01 spaced from the member 93 longitudinally of the bale case, the member |01 having an aperture |08 cooperable with the aperture |02 in the ear |0| to receive a securing means in the form of a bolt |09. The member |00 is thus rigidly carried by the bale case through the medium of the transverse carrier members 93 and |01, the latter serving to reenforce that portion of the bale case bottom wall in the immediate vicinity of the opening 80.

One side of the main body portion of the member 00 is so constructed as to include a longitudinal recess I0 which is parallel to the general longitudinal extent of the bale case. The other side of the member is provided with a similar longitudinal recess Opposite sides of the member |00 respectively carry members in the form of longitudinal strips :not faiiected by flexing of the bale case. seQuentIy, the adjustment of the slot H6 to ac- Amember |00. fxber'lllB is, together with its'side strips [l2 and slots |16 and ||'l include a pair of mountingporations |18 and ||9respectively at that end of the memberxl. which is provided with the mounting pear.v IBI. The opposite end of the member is pror-videdwith a Ypair of spacers :|20 and |2|. The

Vmounting portion H8. and spacer |2|ixcooperate f with bolts |22 and shims |23 to provide means for `Vrigidly but adjustably carrying the strip member I2 on themain body of the member |00. Bolts .1|24aand shims |25v are provided at the other side ofthe member |00 for similarly mounting the `side member .oristrip I3. By meansof the construction just described, the elements defining theslots H6 and ||1. are rigidly related and are Concommodate the needles 86 and 8l, respectively, .canY be made sufciently close to guard ag-ainst lthe wire slipping off the pulley 88 and becoming wedged betweenzthe needles and portions of the Further, inasmuch as the mem- I3, of unitaryconstruction, it may be readily removed and replaced.

The oppositel side portions of the main body `of `the member |00 are apertured at |30 forthe purpose of carrying hay dogs or equivalent retainers, which are not shown since they may be of any conventional construction. The transverse portion ofthe'main body'olc the member I'Sl Eis `liglitened-by an opening |3| and is further .apertured at |32 and |33 for the purpose of accommodating the hay dogs as mentioned above. The function of the saddle member inim- `partingrigidity toV the bale case is complementary fto vthat of Vthe needle `guide member |30, inas- -much as the'depending arms 30 and 3| of the former serve as mounting means for the needle frame 8|fand eliminate the likelihood of the effectoi lbalecase distortion on the needle iframe, --thus maintainingthe general alignment of the -needle frame sothat the needles 86 and 81 may be efficiently guided by the slots I I5 and!
